Cleaning soft box translucent material?
I've got several Elinchrom soft boxes, some getting a little old now, and inevitably they get dirty.
Washing them is easy enough, but doesn't bring back thier bright whiteness that they had when new.
Two are distinctly ivory in colour and I've even tried a weak bleach - well my wife did, ours being a traditional sort of family.
No effect at all.
Any ideas as to how to freshen them up again? Stronger bleach which risks destroying them perhaps?
Or do I bite the bullet and buy some more?
